1. Contribuições ao estudo da fluidodinâmica em leito de jorro: estudos experimentais e de simulação via CFD
O leito de jorro é caracterizado por estabelecer um movimento cíclico e uniforme das partículas em seu interior promovendo, desta forma, um íntimo contato entre as fases. Esta característica em seu escoamento é de fundamental importância industrial, visto que a maioria dos processos requerem uma adequada taxa de transferência de massa e energia. No e

2. Modelagem de fenômenos intempéricos e erosionais em vertentes : uma aproximação de suas componentes não-lineares com base em métodos de mineração de dados / Modeling of soil weathering on hillslopes : coping with nonlinearity and coupled processes using a data-driven approach
This Doctoral thesis aims to explore the relationship between soil physical-chemical properties and relief morphometry, and quantifying these relationships to build conceptual and predictive models. Self-organizing maps and Geographic Information Systems modeling are here used to investigate nonlinear correlations associated with chemical and physical denuda

3. Medida da temperatura de íons em um propulsor a plasma do tipo hall via espectroscopia óptica
Spectroscopy is one of the most used techniques concerning the study of plasma, owning particulary to the fact that it is a non-intrusive method. Others plasma diagnostic techniques with emissive probe and energy analyzers perform the desired measurement but interfere in the field configuration as well as in plasma itself provoking plasma cooling and ions re

4. Alteração e alterabilidade de rochas básicas intrusivas metamorfizadas e filitos sericíticos da região do Quadrilátero Ferrífero e sua implicação no comportamento mecânico / Weathering and weatherability of metamorphised intrusive igneous rocks and sericitic phylites of the Iron Quadrangle and its implication on their mechanical behaviour
The present work presents the results of physical, mechanical and mineralogical study of two rock types commonly found at Quadrilátero Ferrífero region (Minas Gerais State, Brazil). The main purpose of the study was to characterize the weatherability of those rocks when exposed to weathering agents that may cause problems in some civil engineering works, m

5. Paleomagnetic Study of Colider Paleoproterozoic Suite and Associated Mafics, Southwestern Amazonian Craton / Estudo Paleomagnético da Suíte Paleoproterozóica Colíder e Máficas Associadas, Sudoeste do Cráton Amazônico
This work presents a paleomagnetic study perfomed on felsic volcanic rocks of the Colider Suite (5 oriented cores and 42 oriented hand samples, 12 sites), Flor da Serra and Guadalupe mafic rocks (75 oriented cores and 3 oriented hand samples, 11 sites). These units are situated in the northern Mato Grosso State (southwestern Amazonian Craton), close to the A

6. Rare earth and other trace element behaviour in sills and flows from north-northeast region of Paraná Magmatic Province / "Comportamento de terras raras e outros elementos-traço em soleiras e derrames da região norte-nordeste da província magmática do Paraná"
It is presented the determination of rare earth (La, Ce, Nd, Sm, Eu, Tb, Yb and Lu) and other trace (Cs, Rb, Ba, U, Th, Ta, Hf, Co and Sc) element concentrations in 51 representative samples of flows and sills from northern and northeastern Paraná Magmatic Province, particularly those located at north of São Paulo State and south of Minas Gerais. The emplo

7. Avaliação do efeito térmico das soleiras de diabásio nas rochas geradoras da formação Irati (Bacia do Paraná, Brasil) através de técnicas de modelagem numérica / Assessment of the thermal effects of diabase sills on source rocks of Irati formation (Parana, Basin, Brazil) using numerical modeling techniques
To evaluate the thermal maturity and thermal history of source rocks in basins with magmatic activity it is important to consider the thermal effects imposed by igneous intrusions, such as sills and dykes. This work uses the finite difference method for such evaluation, with the transient numerical analysis of heat conduction from Cretaceous diabase sills in

8. Transient convective heat transfer
In nature, as well as within the human-made thermal systems, the time-variable regimes are more commonly encountered, if not always, than the permanent regimes. Nevertheless, studies in convection are still more frequent in the permanent regimes, undoubtedly due to the related difficulties in calculation in terms of time and cost of computation. One may dist

9. MODELAGEM E INVERSÃO 2D DE DADOS MAGNETOMÉTRICOS APLICADOS NA CARACTERIZAÇÃO DA GEOMETRIA DO SINCLINAL GANDARELA E HOMOCLINAL CURRAL QUADRILÁTERO FERRÍFERO, MG
The aim of the present study is the geometrical characterization of Gandarela syncline and Curral homocline, the major structures in the Quadrilátero Ferrífero, based on an integrated analysis of geophysical data. The Gandarela syncline is a reclined fold with NE-SW trending axial trace and hinge zone plunging to southeastern. The Curral homocline is repre

10. Estudos geoquimicos e isotopicos das mineralizações auriferas e rochas associadas da Região de Pontes e Lacerda (MT)
Geochemistry and isotope studies were carried out on the gold deposits of Pontes e Lacerda region (Mato Grosso state, Brazil) where rocks of the Aguapei and Rondoniense mobile belts (SW of Amazon Craton) occur. The stratigraphy of this part of Amazon Craton consists of the Pontes e Lacerda Metavulcano-sedimentar Sequence (PLMVSS), Santa Helena Granite-Gneiss

11. O magmatismo associado ao deposito mineral cupro-aurifero do Igarape, Bahia, Carajas, PA, Brasil
The polymetallic Igarapé Bahia mineral deposit (Cu-Au-Ag-Mo) is hosted by the low-grade metavolcanic and metasedimentary roeles of the Igarapé Bahia Group in the Carajás Mineral Province, northern Brazil. The Igarapé Bahia Group consists mainly of basic volcanic and pyroclastic rocks, psamo-pelitic sedimentary rocks and iron formation, which follow a gen

12. Monitoring Granulation Rate Processes Using Three PAT Tools in a Pilot-Scale Fluidized Bed
The purpose of this research was to analyze and compare the responses of three Process Analytical Technology (PAT) techniques applied simultaneously to monitor a pilot-scale fluidized bed granulation process. Real-time measurements using focused beam reflectance measurement (Lasentec FBRM) and near-infra red spectroscopy (Bruker NIR) were taken by inserting
